RouteTable is created twice with cloudformation - ECS

I am trying to create vpc using cloudformation, with a single public subnet, route table and internet gateway. Problem is two route tables are created in association with the vpc even if I have included just 1 route table.

Below is my code

Description: "Create a VPC with a public subnet, Internet Gateway, and a public route table"
Parameters:
VpcCIDR:
Type: String
Description: "CIDR block for the VPC (e.g., 10.0.0.0/16)"
PublicSubnetCIDR:
Type: String
Description: "CIDR block for the public subnet (e.g., 10.0.1.0/24)"

A VPC will always have a default route table:

> When you create a VPC, it automatically has a main route table. When a subnet does not have an explicit routing table associated with it, the main routing table is used by default.
